Quick Start

Create hierarchical data with TreeItem, add the treeview to your Shiny app UI, and use the selected IDs as needed in the rest of the app.

from shiny import App, ui, render
from shiny_treeview import input_treeview, TreeItem

# Define your tree data using TreeItem objects
tree_data = [
    TreeItem(
        "docs",
        "📁 Documents",
        children=[
            TreeItem("report", "📄 Report.pdf"),
            TreeItem("slides", "📄 Slides.pptx"),
        ]
    ),
    TreeItem("readme", "ℹ️ README.md")
]

app_ui = ui.page_fluid(
    ui.h1("My Tree View App"),
    input_treeview("my_tree", tree_data),
    ui.output_text("selected_item")
)

def server(input, output, session):
    @render.text
    def selected_item():
        return f"Selected: {input.my_tree()}"

app = App(app_ui, server)
